Hi every body,

I would like to develop an very optimized device driver for the USB soundcard, I am going to use the IC TUSB3200 similar the Fast Track Pro from M-Audio (I would like to optimize this device driver as well) , I am a hardware developer, and now I gonna start in the Linux world... I would like to know if someone could tell me what the better path to learn and develop an USB sound card???

if this is a class compliant device, then there is already a driver for it and any work you do to get things working should focus on just making sure that the existing ALSA driver works with whatever "quirks" the device may have.

if it not a class compliant device, why not?
